BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to shoes, and, more particularly, to amulti-function variable healthcare shoe.

2. Description of Related Art

Shoes exhibiting a ventilation effect have some structural problems,even if they may be granted a patent. For instance, a couple of dentsand protrusions are designed to provide a massage function. However,such dents and protrusions circulate the air in the shoes, and are incontact with the skin of feet only, without deeply massaging the archand fascia of feet. When the dents and protrusions perform the massagefunction, the temperature of the air in the shoes increases, whichadversely affect the health of the feet.

Some patents, including U.S. Pat. No. 4,633,597, JP013203, CNZL92233539.7, TW99876, TW64069, IT99876, DE9214653.8, KR29-221886,provide a foot pad having an air sack that obeys pumping principles.

However, some of the foot pads disclosed in the above patents does notestablish a ventilation system, and still suffer from poor aircirculation and cannot achieve the ventilation and massage effectseffectively.

Therefore, how to overcome the drawbacks of the prior art is becoming anurgent issue in the art.

A multi-function variable healthcare shoe of a first embodimentaccording to the present invention comprises a full-sized foot pad 1having a palm-shaped air sack 11, as shown in FIGS. 1A and 1B. The footpad 1 comprises a pad body 10, an air sack 11, a plurality of protrudedair guide 12, and a slot 13.

The pad body 10 is designed to comply with the sole, arch and fasciaelasticity of the foot, to become a full-sized foot pad 1. The pad body10 defines a top face 10 a and a bottom face 10 b, a left side (that isan inner side with respect to the orientation of the foot, and ishereinafter referred to as “an inner side 10 c”), a right side (that isan outer side with respect to the orientation of the foot, and ishereinafter referred to as “an outer side 10 d”), a front end 10 e, anda rear end 10 f. The inner side 10 c, the outer side 10 d, the front end10 e, and the read end 10 f form a side surface of the pad body 10. Thepad body 10 is divided into a heel portion 100 (that carries heel withrespect to the orientation of the foot), a toe portion 102 (that carriestoes with respect to the orientation of the foot) opposite to the heelportion 100, and a middle portion 101 (that carries sole with respect tothe orientation of the foot) disposed between the heel portion 100 andthe toe portion 102. The pad body 10 further comprises a protection edge103 on a side surface thereof. For example, the inner side 10 c, theouter side 10 d, the middle portion 101 and the rear end 10 f of the padbody 10 have a consecutive protection edge 103 on their edges.

The air sack 11 obeys pumping principles. The middle portion 101 isbulged with the air sack 11, and the air sack 11 protrudes on the topface 10 a to become the palm-shaped air sack 11. The air sack 11 and theshoe bottom (not shown) form a compressive space F, as shown in FIG. 1C.Preferably, the air sack 11 extends to the inner side 10 c of a portionof the heel portion 100. The air sack 11 can be integrated with the padbody 10. An intake valve 110 is disposed on the inner side 10 c of anrear bottom portion of the air sack 11, and an exhaust valve 111 isdisposed on the inner side 10 c of a toe portion of the air sack 11. Theintake valve 110 is disposed on the side surface in the bottom portion,is in a concave shape (to form, together with the shoe bottom, anelastic intake mechanism), and is adjacent to the heel portion 100. Theexhaust valve 111 is an elastic valve, disposed on the top face 10 a,and is adjacent to the toe potion 102. The intake valve 110 and theexhaust valve 111 have a valve structure, as shown in FIG. 1A. Theprotection edge 103 has another exhaust valve 103 a corresponding to theintake valve 110 (or the exhaust valve 111), such that the foot pad 1has an appropriate size of exhaust valve.

The air guide 12 is disposed in front of the air sack 11, on the topface 10 a of the pad body 10 corresponding to the exhaust valve 111 andin the toe portion 102, and curvedly extends toward the inner side 10 cand the outer side 10 d, allowing one end to the air guide 12 to beadjacent to the exhaust valve 111, so as to guide the air from the airsack 11 to the outer side 10 d.
